$profiles = $profileApi.GetProfiles([ref] $result)

        Write-Host "$applyProfileResult. Profile not applied."

sleep 10

I tried it but got:

Success. Profile not applied.

Hi, same here, got:

Success. Profile not applied.

I can apply profile successfully from the GUI...

good job,

Same too, not working

it works with xtu 6.4.1.25, not 6.5.xxx

XTU version 7.4.0.26: runnig this is very temperamental

Sometimes it's working and sometimes it's not .
Also, sometimes it's working only with powershell_ise .
Sometimes it's working to apply the "default" profile , but not others ..

I have no clue how to make it to work all the time...

Perhaps Intel have changed some internal stuff? Maybe moved the platform to 64-bit?
Does it make any difference if you stop the XTU service, apply the profile and then start the service?
I don't use the app anymore so I don't have any insights to offer I'm afraid.

I'm running XTU 7.5.2.3. It is installed as an app, rather than a program. It's target is {6D809377-6AF0-444B-8957-A3773F02200E}\Intel\Intel(R) Extreme Tuning Utility\Client\XtuUiLauncher.exe Any idea how to programmatically run this? The typical methods for running an app from the MS Store don't seem to apply here, or aren't apparent.

XTU 6.5.1.371 : I get 'Sucess Profile applied', but it doesn't actually work.

Still have to go into XTU an manually tweak settings each boot to get it to do what I want.

How did you find out which methods to call for the DLL?
If there's a way to find out, I wonder if it'd be possible to also load the IntelOverclockingSDK.dll and apply overclocks, undervolts, etc using the command line this way, now that XtuCli.exe is gone.

The libraries are .NET (managed) assemblies so you can decompile them with ILSpy to see how it works. At least XTU was managed when last used this on 6.5.x.
